Before sunrise, a Booster smart tanker rolls into a fenced fleet yard outside Sacramento. The driver doesn't get out. The vehicles don't move. By the time the dispatcher's first coffee is cold, ninety trucks have been topped off with renewable diesel and the day's routes are already 30 minutes ahead. There is no gas station in this story, which is precisely the point.
Booster sells fuel. That is the boring sentence on the box. The interesting sentence is that Booster is trying to make the gas station optional for a category of customer that has been propping the gas station up - commercial fleets - for about a hundred years.
The problem they saw
If you've never run a fleet, the dirty secret is this - your trucks don't actually want to be at a gas station. They want to be delivering things. Every detour to refuel is a tax: paid in driver-hours, paid in routing complexity, paid in fuel-card fraud, paid in spilled diesel that someone has to mop. The fleet manager's spreadsheet absorbs all of it quietly. Then, at the end of the quarter, the operations VP wonders why margins are thin.
Frank Mycroft, Diego Netto and Tyler Raugh started Booster in 2014 with a thesis that sounds obvious in retrospect and was treated as quaint at the time - the lowest-cost gallon a fleet can buy is the one the fleet never has to drive to. Mycroft, somewhat improbably, came from Planetary Resources, an asteroid-mining outfit. He left a job extracting metals from rocks in space to deliver gasoline in parking lots, which he insists is the more interesting problem. He may be right.
The founders' bet
The bet was that mobile fuel delivery wasn't a gimmick - it was infrastructure. Atoms infrastructure. The kind investors politely avoid because it involves trucks and permits and OSHA. Booster's founders argued the opposite. The physical world was where the inefficiency lived, so the physical world was where the upside lived. Build the truck, build the software, build the safety protocols, and you've built a new layer in the energy supply chain.
The first investors agreed in 2015. Maveron, Madrona, and Version One wrote the seed check. A Series A followed in 2016, then a $20M B in 2017, then a $56M C in 2019. By the time Booster closed its $125M Series D in May 2022, the cap table looked less like a startup and more like an energy-transition consortium - Mitsubishi Corporation, Equinor Ventures, Renewable Energy Group, Rose Park Advisors. These are not people who write checks for delivery apps. They were betting on something larger.
The product, plainly
A Booster smart tanker shows up at a fleet yard, or a corporate campus, or a construction site. It is not a Ford F-150 with a jerry can. It is a purpose-built rig with telematics, leak prevention, audit-grade flow meters, and a quietly impressive amount of software. The driver - a Booster Service Professional - is trained and certified. The flow into each vehicle is recorded, time-stamped, and pushed back to the customer's Fleet Portal.
Smart Tankers
IoT-instrumented fuel trucks. Contactless delivery. Audit trail per gallon, per vehicle, per VIN.
Fleet Portal
Real-time fuel data, telematics integration, emissions reporting and exception alerts for the people who actually run the yard.
Renewable Diesel
Drop-in, lower-carbon diesel. Up to ~70% fewer GHG emissions, with the engine the customer already owns.
The customer doesn't have to buy an EV fleet to participate in the energy transition. They don't have to install a charger. They don't have to negotiate with the utility about an interconnect study. They just have to keep doing what they do, and let Booster swap the molecule.
A Company Built in Slow, Heavy Years
The proof
It is easy to write a manifesto about energy transition. It is harder to deliver 200,000 gallons of renewable diesel and have nobody notice you did it. Booster's California operation has converted more than 60% of its diesel customers to renewable diesel, displacing fossil gallons with biogenic ones at parity with their normal delivery cadence. The conversion is invisible to the driver. The emissions reduction shows up in the customer's ESG report.
Funding Trajectory - The Capital Behind The Trucks
The customer roster is its own argument. Booster fueled Facebook commuters before Facebook had renamed itself Meta. Cisco, Oracle, eBay and PepsiCo trusted them with parking lots in an era when "having a stranger pump gas into your engineer's Subaru" sounded like a confidence trick. The lots stayed quiet. Nobody set anything on fire. The contracts renewed.
The mission, said out loud
Booster's stated mission is to decarbonize transportation by making energy delivery a service rather than a destination. That is the polished version. The unpolished version is: there are millions of light- and medium-duty vehicles in this country that will not be electric this decade, and probably not next decade either. Pretending otherwise is a press release, not a strategy. Renewable diesel, delivered to where the fleet actually parks, is what real-world decarbonization looks like in the meantime.
It is also, conveniently, a real business. Booster pulls in revenue on the order of nine figures, employs around 300 people, and operates across California, Texas, Washington and points in between. Mitsubishi and Equinor do not show up for charisma.
Why it matters tomorrow
The next ten years of fleet operations will be a stack of fuels - gasoline, diesel, renewable diesel, ethanol blends, DEF, eventually hydrogen and electrons - and the customer who has to figure out which blend goes where, in which quantity, on which truck, on which day, will lose their mind. Booster's actual product, the one investors actually bought, is the dispatch layer that absorbs that complexity. The gallons are downstream.
In other words, Booster is building the API for fueling. That is the kind of sentence VCs love and fleet managers ignore, which is fine - fleet managers don't have to care about the API. They have to care that at 5:14 a.m., the truck shows up.

It is 5:14 a.m. again. Same fleet, same dispatcher, same coffee. The detour to the Chevron is gone. The drivers are already heading south on I-5. The renewable diesel is in the tank, the audit log is in the portal, and somebody in compliance is having their first easy morning of the quarter. The infrastructure changed. Nobody had to notice.
That, in the end, is the whole company. Booster is what happens when you decide the gas station is not a building - it's a service - and then you actually do the work to deliver it.
